To converge the conditions of organic water-coal fuel composition combustion in the typical power equipment we developed a new approach and installed an experimental setup, eliminating the traditional fixing the fuel droplets on the thermocouples or rods.Specialized cone-shaped chamber was used to implement the process of lingering of al13sxb30en organic water-coal fuel droplets.Necessary and sufficient conditions for the lingering of organic water-coal fuel droplets were established.We determined the parameters of the system (droplet size of 0.

4-0.6 mm, temperatures 823-903 K and the velocity of the oxidizer flow 1.5-6 m/s) at which the droplets were consistently ignited in the process quick sling heater mount of lingering.Minimum temperatures and ignition delay times of organic water-coal fuel droplets based on brown coal, used motor, turbine, transformer oils, kerosene, gasoline and water were defined.
